Positive OPK? 17 months post partum/ no period

17 months post partum mama w/ no period due to breastfeeding my toddler. I have no way to know if I am ever ovulating. I have had probably 10 positive OPK’s in the last four months but I haven’t gotten a period (and no spotting either), and always get BFN. DESPERATELY want baby #2 since I am an older mama and started late.

I took a HCG test just for fun and made sure I didn’t put it close to the OPK. I’ve heard of dye run before.

Any advice????
